In the past, I have found the quite often, too often, the disk errors  
happened in the 1st sectors of the disk (and I still have to reboot  
often).  It does not look good when losing a whole disk, eh?

Assume 3 disks, A, B and C.
Each stripe would be on these disks:
A+B
C+A
B+C

C+A
B+C

Maybe not exactly as above, but if not, something similar.

It will?  How?  Does it just make the last mirror "pair" have 3
disks or what?

If so then wouldn't it be better just to not have that disk under
md and use it for someting else?
